CSS for - Gallery / Carousel Viewport Height for Mobile

Hey friends! 

I'm currently building out my new website and learning a lot. Especially CSS. I've built out the homepage and have a featured work section that on desktop is great (would like to know the css to change the height) but on mobile the Gallery is far too small and I would like to increase the height. Please help?

Try some CSS like this

/* resize top slideshow */
@media screen and (max-width:767px) {
body.homepage .gallery-block, body.homepage .gallery-block .slide, body.homepage .sqs-gallery-design-stacked {
    height: 350px !important;
}
    body.homepage .gallery-block img {
        top:0 !important;
        height: 100% !important;
        left: 0 !important;
    }
}
